My 7 had swirl marks all over the place and after trolling on a couple of car care sites I ordered a Meguiars DA buffer. Well after one use the results are awsome. All swirling is gone, paint looks clean.

Took about 3 hours but worth it. Only problem was I dont have access to power so I got an inverter off ebay and buffed in the park...in the shade.

 

Looks good, what polish(s) did you use?

 

Wash, clay, polish and then waxed.
Meguiars line.
